MATRIX-MAGAZINE FOR TYPOGRAPHICAL MACHINES.

Patented June a; 1915.

Application filed February 19, 1914. Serial No. 819,754.

for Typographical Machines, of whichthe following is a specification.

' My present invention relates to improvements in typographical machinesand more especially to those of the linotype class wherein the matricesfrom which the lines of type are cast are stored in a magazine.

It'is customaryto place such magazines in an inclined position on themachines, the upper end of the magazine being normally open to receivematrices from the distribut-v ing mechanism and the lower end of themagazine having means for delivering the matrices to the matrixassembling mechanism. At times it is desirable to remove a magazine fromthe machine and to'substitute another magazine containing a difi'erentfont of matrices, and in doing this the magazine is liable to becomeinverted. or tilted.

zine with means to preventaccidental escape or spilling of the matricesfrom the upper or matrix-receiving end thereof.

The primary objects of the present in vention are to so construct themagazine as to prov1de means which will escape of matrices therefrom,such means being contained within the length of the magazine and havingno. projecting parts to increase such length, thereby avoidinginterference with the distributing mechanism, and to facilitate andcheapen the manufacture of the magazine.

To these and other ends, the invention consists in certain improvements,and combinations and arrangements of parts, all as will be hereinaftermore fully described, the novel features being pointed out particularlyin the claims at the end of thespecification.

In the accompanying drawing :-Figure' 1 is a perspective v1ew of theupper ri hthand corner of a magazine constructe in accordance with thepresent invention; Fig. 2 represents a longitudinal section of the samein partially inverted position; Fig. 3 is a view of the upper right-handcorner of prevent the the magazine with the upper plate thereof removed.

Similar parts are designated by the same reference characters in theseveral views.

The present invention is shown by way of example as applied to matrixcontaining magazines of the type generally employed in connection withtypographical machines ofthe linotype class.

. It will be understood, however, that the invention is not restrictedto the precise construction shown, as equivalent constructions withinthescope of the claims at the end of the specification may be used andwill be included thereby.

The magazine, as shown, comprises top and bottom plates 1 and 2 whichare spaced to accommodate the matrices in edgewise position betweenthem. The inner faces of the plates 1 and 2 are grooved to form channels3 and 4.- which receive the' upper and lower ears on the matrices andthereby guide the latter. In the normal position of the magazine on themachine the inclinationof the magazine is sufiicient to, cause feedingof the matrices by gravity to the lower or dehvery end thereo itbeingcustomary'to .control the delivery of matrices-from the lower end of themagazine by escapement devices which are well known in this art.

It is customary in machines of this class to provide distributingmechanism for re- I greater than the distance between the matrixchannels in the magazine, and in. order to insure the ,proper entranceof the matrices into their appropriate channels in the magazine theupper ends ofthe matrix-receiving channels are usually flared orwidened, as at 5 in Fig. 3. In manufacturing-magazines wherein .thematrix-receiving channels areflared'or widened at their upper ends,difiiculty is experienced in forming the flared or widenedportions ofthe channels Where the widened portions thereof are formed on the sameplates which constitute the body of the magazine, owing to the necessityof interrupting the action of the cutting tools which flare or widen thechannels before such tools strike the opposite, sides or walls of thechannels, it being understood that the cutting tools which Widen orflare the channels operate at an angle to the length of the straight andrelatively long channels.

According to the present invention, this difliculty is avoided byforming the widened or flared portions of the channels in plates 1 and 2which are separate from the plates 1 and 2 although they practicallyform continuations of those plates, and the total length-of the magazineis the same as where the flared or widened portions of the chan nels areformed in integral parts of the top and bottom plates of the magazine.By forming the flared or widened portions of the channels in separateplates, the operation of producing the same is obviously facilitated andcheapened as the cutting tools may move across the separate plateswithout injury to any part of the magazine. By so constructing themagazine, the plates l and '2 can be, utilized as locks to preventescape of matrices from the upper end of the magazine when the same isinverted. To accomplish this, the plates 1 and 2 are mounted on hingepins (3 and 7, these hinge pins being supported by hinge members 8 whichmay be fastened at suitable intervals to the plates 1 and 2 of themagazine, the complemental hinge members 9 being secured to the upperand lower sides of the plates 1' and 2 respectively.

When the magazine is in operative position, the plates l and 2 are inalinement with and form substantially unbroken continuations of theplates 1 and 2 of the magazine, thus affording an unobstructed openingthrough which the matrices may pass from the distributing mechanism intothe appropriate channels of the magazine. The

plates l and 2 are shown in such position in Fig. l of the drawing.

When it is desired to remove the magagine from the machine, the plates 1and 2 are moved toward one another and they will then prevent the escapeof any matrices from such end of the magazine, it being understood thatthe plates 1 and 2 extend across the upper end of the magazine wherebythey will control all the matrix channels thereof. Fig. 2 shows theplates 1 and 2 in a position to prevent escape of the matrices.

Means is provided by the present invention for retaining the plates 1and 2 either in normal position to permit matrices to enter the magazineor in a position to prevent the escape of matrices.

In the construction shown, the end hinge members 9 at both sides of themagazine are provided with projections 10, and catches l]. are pivotedon pins or screws 12 on the top and bottom plates 1 and 2 whereby thesecatches will swing laterally. When the mag azine is in normal positionon the machine, the catches 11 will engage between the projections 10and the plates l and 2 respec tively and will thereby hold said platesin alinement with the channeled plates land 2 of the magazine. When themagazine is to be removed from the machine, the catches 11 are releasedand then brought into position to engage above and below the projections10 on the plates 1 and 2 respectively, as shown in Fig. 2, said platesbeing then held in positions to prevent the escape of matrices.

Springs 13 are shown for retaining the catches 11 in either of thepositions mentioned, and the side plates 14 at each side of the magazineand which serve to hold the plates 1 and 2 in proper spaced relation arenotched as'at 15 to permit the plates l and 2 to swing toward oneanother, as shown in Fig. 2.

By so constructing the magazine, the manufacturing of the magazine isfacilitated and cheapened and, furthermore, the length of the magazineis not increased as the plates containing the flared or widened portionsof the channels are parts of the main channeled plates, and by movablymounting the plates containing the widened portions of the channels,simple and eflicient means is provided for preventing escape of matriceswhen the magazine is partially or completely inverted.
